#     * tag 'dma-mapping-6.10-2024-05-20' of git://git.infradead.org/users/hch/dma-mapping:
#       dma: fix DMA sync for drivers not calling dma_set_mask*()
#       xsk: use generic DMA sync shortcut instead of a custom one
#       page_pool: check for DMA sync shortcut earlier
#       page_pool: don't use driver-set flags field directly
#       page_pool: make sure frag API fields don't span between cachelines
#       iommu/dma: avoid expensive indirect calls for sync operations
#       dma: avoid redundant calls for sync operations
#       dma: compile-out DMA sync op calls when not used
#       iommu/dma: fix zeroing of bounce buffer padding used by untrusted devices
#       swiotlb: remove alloc_size argument to swiotlb_tbl_map_single()
#       Documentation/core-api: add swiotlb documentation
